Man / Woman
What is the cause of domestic violence? The male is usually the perpetrator, so it is surely he who is to blame. There is no excuse for his ever harming another human being, no matter how great his burden of stress and pain.
Simply, violence is the natural manifestation of the dominant emotions, and will continue for as long as the emotions which fuel it. Now hear me: if men and women stopped playing the games of submissiveness and dominance I guarantee you, there would be no more violence. Mind you, neither would there be any love, for love is precisely a game of dominance and submission.
If a woman submits her will to a man, even in the slightest, just for fun, then she fuels his dominant emotions. This is truly playing with fire.
